Our data support the hypothesis that polyP is the major P species translocated in the tubular vacuolar network, the presence of which was previously demonstrated in AM fungi. The rapid synthesis of polyP might be important for the maintenance of effective hyphal P uptake.PolyP considerably exceeded amounts of vacuolar inorganic P, where it was located in acidic, presumably vacuolar compartments, and had a short average chain length. These P metabolites also appeared in the roots, but later. A time-course study of P-starved external hyphae supplied with additional P showed that polyP appeared more rapidly than vacuolar inorganic P.

In vivo 31 P NMR spectroscopy was used to characterize polyP and other P pools in external hyphae and in mycorrhizal roots of associations between Glomus intraradices and cucumber (Cucumis sativus).

Here, we applied noninvasive and nondestructive nuclear magnetic resonance (NMR) spectroscopy to obtain novel information on AM fungal polyP.

Polyphosphate (polyP) is presumably central to phosphate (P) metabolism of arbuscular mycorrhizal (AM) fungi, but its synthesis, location and chain lengths are poorly characterized.
